Answer:
= 5x-5y
Step-by-step explanation:
Multiply 5to x and y
Answer:
x = 36°
Step-by-step explanation:
Where a transversal crosses parallel lines, any obtuse angle it creates is supplementary to any acute angle it creates:
3x +2x = 180°
5x = 180° . . . . . . . . . collect terms
x = 180°/5 = 36° . . . . . divide by 5
Answer:
x = +-sqrt(3) and they are the actual solutions
Step-by-step explanation:
x^2/ (2x-6) = 9/(6x-18)
get a common denominator of 6x-18
x^2/ (2x-6) * 3/3 = 9/(6x-18)
3x^2/ (6x-18) = 9/(6x-18)
since the denominators are the same, the numerators must be the same
3x^2 = 9
divide by 3 on each side
x^2 = 3
take the square root of each side
sqrt(x^2) = +-sqrt(3)
x = +-sqrt(3)
You have a 33.33% chance to get it right each time
multiply 33.33%*33.33%*33.33%= .3333*.3333*.3333
it equals about 4%
